Two days after Drake London scored the go-ahead touchdown on "Monday Night Football" and celebrated by pantomiming shooting a gun into the air, the Atlanta Falcons wide receiver said he wasn't pleased with how it all went down.

Falcons wide receiver Drake London was penalized after catching a touchdown pass in the final minute of Atlanta’s 22-21 victory in Philadelphia on Monday night for pretending to shoot in the air, a violation of a longstanding NFL rule that prohibits such gestures.

Falcons Coach Raheem Morris calls London pretending to fire a gun – about a week honoring victims of a school shooting near Atlanta – 'a mistake.'

Atlanta entered the season expecting to field a high-powered aerial attack. It struggled in the season opener, as nine-figure free agent quarterback Kirk Cousins went 16-of-26 for 155 yards, one touchdown and two interceptions.

Kirk Cousins led a flawless last-minute drive for Atlanta and connected with Drake London for a 7-yard touchdown with 34 seconds left to give the Falcons a 22-21 victory over the Philadelphia Eagles.

The Atlanta Falcons got a massive win on the road against the Philadelphia Eagles earlier this week, scoring a late touchdown to clinch the game. Anytime a team can grab a victory on the road is special but it's especially meaningful when it comes on Monday Night Football.
